FLUSHING APPARATUS.

Application filed May 8, 1917.

To wll wltom. it may concern Be it known that T, EDWARD H. Govn, a.

citizen of theUnited States, residing at Bid.-

deford', in the/county of York and State of.

whichthejfollowing is a specification.

This invention. relates to improvements in flushing apparatus. It is specially designed for use, in connection with water closets. Whilev it is also adapted for use in connec. tion. with high-tank closets, it is specially adapted for use in connection with low-tank closets. 7

Its construction is such: as to overcome certain objections which have hitherto been incident to low=tank closets. It. is designed to rendersiphonaction certain, perfect, adjustable, adequate and practically noiseless, the latter afeature long sought for, but hitherto unattained in low-tank closets. It does away with the great waste of water and expense of frequent repairs incidental to the under-water valve now in generaluse. It imparts momentum to the water through an unobstructed waterway, giving a perfect flushing of the bowl. It makes impossible any overflow of the tank with its resulting damage.

In the drawings herewith accompanying and forming a part of this application, Figure 1 is a vertical sectional view of a tank and of my improved flushing apparatus mounted therein, the removable short leg being in section; Fig. 2 is a horizontal sectional view taken on line 00-00; Fig. 3 is a vertical sectional view of a somewhat modified form of the flushing apparatus, and Fig. 4 is an elevation of the opposite side of the short leg.

The same reference characters indicate like parts in the several figures.

In said drawings 1 is a water tank adapted to contain the flushing apparatus. The flushing apparatus consists of a so-called bell siphon having a long leg 2 adapted to pass through the bottom of the tank and to the bowl and a short leg 3 terminating in the tank. As shown in Fig. 1, the top 4t of the long leg is flaring. The short leg is adapted to be placed down over the long leg and to be seated in a recess 5 formed in a flange 6 integral with the long leg on the back and sides thereof and it may be supported against backward movement by a bar 7. The short leg may be made of any suitable ma- Specification of Letters Patent.

terial and the upper end 8 is contracted and the lower end 9 is formed at the front vertically in the arc of a circle. Pivotally mount ed in a bearing 10 on the front of the long leg is a'device for starting siphon action. This consists of a pivoted piston made in two members, one 11 fixed on a pivot 12 mounted in the bearing and the other or outermember 13 pivotally attached to theformer by pivots, 1 1 in projecting arms 15, the two members being of the same width and together being of the same length as the short leg and when extended filling the enlarged or curved part of the short leg with a close fit. The pivot 12, on. which the piston is mounted, is provided with a crank 16, by means of which the piston may be raised. is filled. to the proper height, which is just below the open end of the long leg, the apparatus is ready for use. The two members of the piston are then extended at or near.

the lower end of the short leg. When raised it lifts a body of water in the short leg which passes over into the upper end of the long leg and siphon action begins. As soon as siphon action begins an upward current is induced in the short leg which swings the outer member upwardly on its pivot and allows free passage of water from the tank up through the short leg and over into the long leg. The inner member of the piston is provided with a stop 17 which limits its upward movement beyond a point where gravity would cause it to fall back into down position automatically when power is removed, and the outer member is eccentrically pivoted to the inner member so that when in down position it will automatically by gravity assume an extended position, stops 18 limiting the turning movement of the outer member relative to the inner member. ()ne side of the short leg is provided with a recess 20 to allow it to seat down over the crank arm and make a tight fit. The short leg is adapted to be locked in position relative to the long leg by a latch 21 pivotally attached to one leg and adapted to engage a pin 22 on the other leg. To adjust the amount of water to be delivered at each flushing, I aflix a pipe 23 to the upper end of the short leg and provide its lower end with a vertically adjustable section 24 which will let air into the short leg as soon as the water in the tank falls below the lower end of the pipe wherever it may be adjusted.

In Fig. 3 I have illustrated the application of my apparatus toa siphon of ordinary construction except that the lower end of the short leg is'similar to that shown in Fig. 1. Its'operation, however, is substantially the same asin the former case.
